[Elecraft] KPA1500 PA Current

[Edward R Cole]

In the same vein:  I recently tried out my new 2m 1500w sspa at 750w 
in SSB and stations on my net only stated a slight increase in signal 
100 miles away vs running 130w.  That should have indicated more than 
one s-unit stronger (10Log (750/130)=7.6 dB).

Definitely a "knee" in signal strength where change is most 
significant and where change above is not so much.  HF that should 
even be more compressed.

Raising antenna ten feet above tree top is worth at least 10-dB in 
signal improvement at VHF (and way more as freq is increased into 
UHF+).  I can lower my 2m array to 4-foot AGL by use of a 
winch.  Going from there to about 40-feet (tree top) is worth maybe 5-dB.
